席状砂 meaning in Chinese
sand sheet
sheet sand
Examples
- The analysis of primary oil distribution shows the base - level controlled oil distribution in reservoir . in this paper , subjects as following are discussed in detail
而构成储层的则主要是沟道、沟道间和席状砂体。 - Sand bar sub - facies of lagoon , front delta , sheet sandstone of offshore sea are the best sedimentary facies belts for the oil & gas accumulation
泻湖相堡坝亚相、三角洲相前缘亚相以及滨海相席状砂亚相是砂岩储层分布和发育的最有利相带。 - Considering all factors in trap - forming , the most prospective reservoirs are the sub - water channel sandstones , the front sheet sandstones of braided delta and bedded turbidity sandstones . the petroleum exploration targets are identified further
综合成藏要素进一步研究，认为水下分支河道、辫状三角洲前缘席状砂和小型层状浊积砂体是比较有利的储集体。 - According to the abundance well logging , mud logging and core analysis data , gaotaizi reservoir has been classified into four sand group with the principle of cycle comparison and classified control . based on the detailed study of lithologic character , sedimentary structure , paleontologic fossils , depositional sequence , rock association and logging data , the microfacies of the studied area are divided into such seven types : subaqueous distributary channel microfacies ; river mouth bar microfacies ; subaqueous interdistributary channel microfacies ; subaqueous crevasse channel microfacies ; subaqueous natural barrier microfacies ; distal bar microfacies ; delta front sheet sand microfacies . the characteristic of each sedimentary microfacies are described detailedly
通过研究大量测井、录井资料和岩芯资料，依据“旋回对比，分级控制”的原则，把研究区高台子油层划分为g 、 g 、 g 、 g四个砂层组。通过对研究区岩性、沉积构造、古生物、沉积序列、岩石组合及测井曲线特征进行研究的基础上，认为研究区高台子油层属于三角洲前缘亚相沉积，并将研究区沉积微相划分为：水下分流河道、河口坝、水下分流河道间、水下决口扇、水下天然堤、远砂坝、席状砂等七种微相类型。 - Using sedimentary facies analytical and formation inverse technique , the depositional characteristics and distribution of dujiatai formation of this area were described , disclosing that delta front facies and prodelta facies were mainly developed in dujiatai formation . material source are mainly from southern and northeast of the working area . sand types are mainly of delta front subwater distributaries channel sand body , river mouth bar and sheet sand body with large degree of planar variation
2 .采用沉积相分析及储层反演预测技术，对新齐14井区杜家台油层储层沉积特征及展布特征进行了详细描述，揭示出本区主要目的层杜家台油层属t -扇二角洲沉积，发育扇三角洲前缘亚相及前扇三角洲亚相，物源主要来自于工区南部及东北部，发育的砂体类型土要为扇三角洲前缘水下分流河道砂体、河口坝砂体及席状砂砂体。
